Reminiscent of a Reese's Peanut Butter Cup, this peanut butter hot fudge with swirls of creamy peanut butter in warm hot fudge is a decadent topping for ice cream.
In a small saucepan, combine sugar, cocoa and flour with a whisk. Stir in milk and butter.
Bring to a boil over medium high heat, stirring continuously, and boil 2-3 minutes or until thickened.
Remove from heat and stir in vanilla. Add peanut butter, and lightly stir, leaving swirls of peanut butter, If desired,
Hot fudge thickens a bit more as it cools. Store it in the fridge and warm up how much you want, when you want it, in the microwave. It heats up really fast, so microwave in 10 second increments.
Notes
You can use non-fat milk or 2% but whole milk is better. Your choice!
Substitute any nut butter including almond, hazelnut, sunflower, etc. Nutella would be good, too.
